教育的最高目标是培养公民的道德与心灵习性

美国面临国内外前所未有的挑战，公立学校必须作出更多努力，以培养年轻人成为“为了所有人的自由和公正”的坚定倡导者。诚然，阅读和数学是重要的，但最重要的是什么样的人在学习阅读和数学。     

On equitable cake-cutting, or: caring more about caring

It is obvious that the values of women differ very often from the values which have been made by the other sex. It is the masculine values that prevail.
Virginia Woolf
A Room of One's Own
Getting hold of the difficulty deep down is what is hard. Because if it is grasped near the surface, it simply remains the difficulty it was. It has to be pulled out by the roots, and that involves our having to think about these things in a new way. The change is as decisive as for example, that from the alchemical to the chemical ways of thinking. The new way of thinking is what is so hard to establish.

Limits of search filter development

Objective

The research attempted to develop search filters for biomedical literature databases that improve retrieval of studies of clinical relevance for the nursing and rehabilitation professions.

Methods

Diagnostic testing framework compared machine-culled and practitioner-nominated search terms with a hand-tagged clinical literature database.

Results

We were unable to: (1) develop filters for nursing, likely because of the overlapping and expanding scope of practice for nurses in comparison with medical professionals, or (2) develop filters for rehabilitation, because of its broad scope and the profession''s multifaceted understanding of “health and ability.”

Conclusions

We found limitations on search filter development for these health professions: nursing and rehabilitation.     

Development of Scientific Thinking Facilitated by Reflective Self‐Assessment in a Communication‐Intensive Food Science and Human Nutrition Course

A one‐credit seminar on controversies in food science and human nutrition was a platform to introduce students to learning frameworks for thinking‐like‐a‐scientist. We hypothesized that explicitly engaging students in thinking about their thinking abilities within these frameworks would enhance their self‐perception of scientific thinking, an important general ability for food scientists. Our objectives were to assess thinking‐like‐a‐scientist using a student self‐assessment survey, and analyze their self‐reflections for evidence of such thinking. For students enrolled in one of the offerings of this course among 5 semesters from 2012 to 2014, differences in scores on a survey instrument for thinking‐like‐a‐scientist from the beginning to the end of the course showed gains in self‐assessed abilities (N = 21 to 22 students/semester). In each of the first 2 semesters in which we introduced thinking‐like‐a‐scientist frameworks, students thought they were better at defining problems scientifically by 13% to 14%. In the 3rd course offering, students’ self‐assessment of their abilities to seek evidence improved by 10%. In the 4th and 5th semester course offerings, students’ self‐assessed abilities to develop plans based on evidence improved by 7% to 14%. At the end of each semester, students’ self‐reflections on scientific thinking (N = 20 to 24/semester) included specific reference to asking questions (45% to 65% of reflections) and making plans based on evidence (26% to 50% of reflections). These data support the usefulness of self‐reflection tools as well as specific learning frameworks to help students to think about and practice thinking‐like‐a‐scientist.     

Abusive and nonabusive mothers' ability to identify general and specific emotion signals of infants

Slides depicting infants in 7 different emotion states were shown to 20 abusive mothers and to 20 matched, nonabusive mothers. The ability of these subjects to identify general emotional affect (positive and negative) and specific emotion signals was tested. Results indicated that abusive mothers were more likely than the comparison group to incorrectly identify specific emotion signals and to label negative affect as positive.     

Reducing the Academic Risks of Over-Optimism: The Longitudinal Effects of Attributional Retraining on Cognition and Achievement

Although optimism is generally regarded as a positive dispositional characteristic, unmitigated optimism can be problematic. The adaptiveness of overly optimistic expectations in novel or unfamiliar settings is questionable because individuals have little relevant experience on which to base such expectations. In this four-phase longitudinal study we examined over-optimism in students when making the transition from a familiar academic setting (high school) to a novel academic setting (college). In particular, we focused on the efficacy of attributional retraining (AR), a control-enhancing intervention, to ameliorate the scholastic transition of overly optimistic students in terms of academic-related causal attributions and control perceptions, course grades, and overall GPAs. Results suggest that overly optimistic college students who did not receive the AR intervention increasingly endorsed maladaptive causal explanations for academic performance, and performed at the same level as students with extremely low optimism. Conversely, as expected, over-optimists who received the AR intervention significantly increased in their use of adaptive causal explanations and perceptions of control, in addition to academically outperforming the no-AR/over-optimists. These findings indicate that the potential risks associated with over-optimism may be reduced by pairing optimism with AR to induce adaptive cognitions, thereby facilitating achievement.     

Non-organic failure to thrive: Decision for and videotaped evaluations

Infants hospitalized for non-organic failure to thrive in the first six months of life are in a life-threatening situation and are already at risk for poor bonding with mother. In light of this, the meaning and use of foster care and how this separation affects the developing mother-child relationship are the issues addressed through examination of 16 cases in which 8 of the infants were placed in foster care and 8 discharged home after the failure to thrive hospitalization. This paper examines (1) maternal histories of pregnancy, labor and delivery and the neonatal status of placed and non-placed infants; (2) the developmental and weight status of placed children; (3) the nature of the decision criteria for after-hospital care; and (4) the mother-infant relationship at initial intake in terms of mother's report of events and observations of feeding and play interactions during a videotaped assessment process. The study found that the interactions between mother and infant in those situations which required foster care were clearly more dysfunctional when compared to those in which the baby was discharged home to mother. Babies in the two groups were comparable in weight status at the time of hospitalization although babies in foster placement had slightly lower scores on the Bayley Scales. Maternal histories of pregnancy, labor, and delivery were similar for the two groups as were the birth and neonatal histories of the infants.     

Increasing explanatory behaviour,problem-solving,and reasoning within classes using cooperative group work

The present study builds on research that indicates that teachers play a key role in promoting those interactional behaviours that challenge children’s thinking and scaffold their learning. It does this by seeking to determine whether teachers who implement cooperative learning and receive training in explicit strategic questioning strategies demonstrate more verbal behaviours that mediate children’s learning than teachers who implement cooperative learning only. The study also sought to determine whether students who receive training in explicit questioning strategies demonstrate more explanatory behaviour than their untrained peers, and, as a consequence, do these same students demonstrate more advanced reasoning and problem-solving skills on follow-up reasoning and problem-solving tasks. The study involved 31 teachers in two conditions, the cooperative + strategic questioning condition and the cooperative condition, and two groups of students from each teacher’s classroom. The results show that the teachers in the cooperative + strategic questioning condition used significantly more mediating behaviours than their peers in the cooperative condition. The study also showed that the children in these teachers’ classes engaged in more elaboration and obtained significantly higher scores on the follow-up reasoning and problem-solving tasks. The study demonstrates the importance of explicitly teaching strategic questioning strategies to children during cooperative learning.     

Representational Abilities and the Hearing Status of Child/Mother Dyads

Two representational abilities, expressive and receptive language and symbolic play, were assessed in multiple formats in hearing and deaf 2-year-old children of hearing and deaf mothers. Based on maternal report, hearing children of hearing and deaf mothers produced more words than deaf children of hearing mothers, hearing children of hearing mothers more words than deaf children of deaf mothers, and deaf children of deaf mothers more words than deaf children of hearing mothers. Based on experimenter assessments, hearing children in both groups produced and comprehended more words than deaf children in both groups. By contrast, no differences emerged among these groups in child solitary symbolic play or in child-initiated or mother-initiated child collaborative symbolic play; all groups also increased equivalently in symbolic play between solitary and collaborative play. Representational language and symbolic play were unrelated in hearing children of hearing mothers and in deaf children of deaf mothers, but the 2 abilities were associated in children in the 2 child/mother mismatched hearing status groups. These findings are placed in the context of a proposed developing modularity of verbal and nonverbal symbol systems, and the implications of hearing status in communicative exchanges between children and their mothers in diverse hearing and deaf dyads are explored.
